SPECIFICATION forming part of Letters Patent No. 234,583, dated November 16, 1880.

Application led September 6, 1880.

.To all whom it may concern:

Be it known that I, LYMAN M. KANAVEL, of Nashville, in the county of Holmes, and in the State of Ohio, have invented certain new and useful Improvements in Pumps and I doliereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification. A

This invention relates to certain improvements in 'orcepumps; and it has for its object to provide a pump that will be cheap and simple in construction, eicient in operation, and which can be readily applied to any well or other water-supply. These objects I eft'ect by means of the apparatus illustrated in the accompanying drawings, in which- Figure l represents a perspective vicw of my pump entire. Fig. 2 represents a sectional view through the pump-cylinders, and Fig. 3 represents a top View of one ofthe pumpeylinders The letter A indicates two pump-cylinders, open at the tops and closed at their bottoms, the said cylinders being designed to be sub merged in a well, cistern, or other watersupply. The said cylinders connect, by means of inclined pipes B, with a vertical discharge or educt pipe, O. The said pipes B are enlarged between their ends, and are provided with ballvalves D. To one of the cylinders are attached two uprights, E, which are connected at their upper ends to thc tube O by means 0f braces F, and between the said two uprights is supported a cross-piece, Gr, having a guide-aperture, H, through which the piston-rod I of the pump passes.

rIhe letter K indicates a crank-shaft `journaled at L in the uprights, one crank of said (No model.)

shaft being connected with the piston-rod before mentioned by means of a link, M. The other crank or winch is provided with a handle, N, by which the shaft can be conveniently rotated. The piston-rod I before mentioned connects with another piston-rod, I, by means of a lever, O, fulcrumed to the tube C, so that the said piston-rods will opera-te their pistons in opposite directions.

lhe letter l? indicates the pistons, which are loca-ted in the respective pump-cylinders. Said pistons consist bf short cylinders open at both ends, the said cylinders being each provided with a cross-piece, Q, near the top, to which are hinged downwardly-opening apvalves R. The said cylinders are also provided with annular shoulders S near their tops, forming seats for said valves. The piston-rods I are secured to loops T, secured to the respective cross-pieces of the pistons.

The operation of my invention will be readily understood from the above description and accompanying drawings without further explanation.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination, in a pump, of' the cylinders A, connecting-tubes B and their valves, educt-tube C, uprights E, crank K, guide-piece H, piston-rods I and their pistons, and lever O, all constructed and arranged substantially as and for the purposes specified.

In testimony that I claim the foregoing I have hereunto set my hand this 30th day of August, 1880.
